Navy-LANTDIV approached Bhate with the concept to deconstruct
and close a Biological Treatment Cell (BTC) without developing
traditional plans and specifications. Given the nature of
the removal, the Navy wanted to remove the cell, backfill,
re-grade, re-shape, and restore the site without going through
the traditional design-bid-build process. The Navy estimated
that this approach would potentially save over $100,000 in
design and procurement costs. Since the future land-use for
the site has not been determined, restoring it to exacting
standards was not necessary. However site drainage was of
paramount concern because of its proximity to an oil/water
separator that discharges into the Elizabeth River. Understanding
the Navy’s approach (no design, no specifications, no
construction drawings, no cut/fill volume quantities), we
worked closely with the Navy to develop the scoping strategy
for the site and negotiated a firm-fixed price Delivery Order.
 After
developing a conceptual-type work plan, we quickly mobilized
to the site. Our first challenge was to remove approximately
10,000,000 gallons of rain water from the cell. Analytical
testing confirmed the water was suitable for discharge. We
overcame this by draining the cell dry of fluid with pumps
while monitoring the discharge with a Horiba meter. After
breaching the cell berm in a controlled manner, we removed
and disposed of approximately 600,000 square feet of 60-mil
HDPE liner, emolished/scrapped two-50,000 gallon ASTs, backfilled,
and graded the site. The placement of topsoil and hydro-seeding
were completed. This project is considered a “showcase”
by the Navy for the outstanding cooperation and trust between
the Government and the contractor as well as the cost savings
realized over the traditional type of procurement.
